[Abstract]:UHV transmission technology is the need of the current national power grid development strategy. With the continuous upgrading of line voltage, the span between stations becomes larger and larger, and the optical signal will decay with the increase of transmission distance. This brings new difficulties to power system communication, so the study of reliable long distance optical transmission system is of great significance to power grid construction. In this paper, the key problems of ultra-long station distance optical transmission in power system are studied from three aspects: line loss, dispersion and limited optical signal-to-noise ratio. The 400km ultra-long station distance optical transmission is realized by optical relay and remote pump (non-optical relay). In particular, a "self-contained" independent power supply optical relay device installed in the tower is proposed to realize the super-long distance optical communication. The single-wave 10G optical transmission system was deployed and tested on the 鹵800 kV UHV line from Hami to Zhengzhou (Shicheng-Huanxian section). The link loss, joint loss, dispersion loss and the receptivity of the equipment are calculated in detail, and the predetermined distance between the optical amplifier and the gain unit in the engineering is determined. During the implementation of the project, the position of the pole tower of the optical relay station and Raman remote gain unit is determined in accordance with the limit of optical loss according to the previous calculation, and the system is deployed and verified in the actual production environment. The transmission distance above 400km is realized in both systems. Finally, the two systems are tested and compared. The research results show that the optical communication transmission between substation and substation in UHV transmission line can be realized, which is of practical significance for future engineering construction and scheme design and popularization.
